The Kirksville man accused of murder in a horrific case that reportedly involved him throwing human arms at witnesses is facing more serious charges after new information was received by investigators.

Paul R. Potter, 49, of Kirksville, is now facing a class A felony of first-degree murder, a class C felony of first-degree tampering with a motor vehicle, a class C felony of second-degree arson, felony armed criminal action and a class B felony of burglary in the first degree.

Potter was scheduled to appear via the video link between the courthouse and Adair County Jail, where he is being held on a $1 million bond, for his preliminary hearing setting Wednesday morning.

Potter is charged with murdering his neighbor, Willis Edward Meredith, on Jan. 6 in Meredith’s apartment on Valley Forge Drive. Potter was Meredith’s neighbor at the Village 76 community.

Documents state Potter committed the crime “after deliberation.” The probable cause statement indicates Potter told police he “proceeded to the victim’s apartment out of anger” and brought several knives to confront Meredith. He then stabbed Meredith in the head and face.

Documents state a contributing cause of death was “sharp force wounds” to the left lung and heart.

Potter also reportedly dismembered Meredith’s body and threw his victim’s arms at witnesses while authorities responded to a vehicle fire they believe Potter set in order to conceal the murder.

Tuesday, nine days after the horrific crime, authorities were finally able to reveal the murder victim’s identity. Adair County Coroner Brian Noe said last week the victim’s injuries made a visual confirmation impossible, and the victim’s fingerprints were sent to the Integrated Automated Fingerprint Identification System (IAFIS).

Noe was able to reach a conclusion without the results of that analysis, contacting Meredith’s family members who were able to confirm locations and details of various tattoos.

IAFIS results were returned Tuesday, further confirming Meredith’s identity.

Meredith also went by the alias “Jake Steadman” and lived in the Novinger area for about 30 years before moving to Village 76.

Noe said he was not able to release information about Meredith’s family, and noted they and Meredith had been “estranged” for many years.

Meredith was born in Iowa and lived in the Kansas City area before moving to Novinger in the mid-1970s.
